IEC60909-0 Section 4.3.1.2 c) recommends Method C for calculating the peak short-circuit current in meshed networks.
See IEC Technical Report TR 60909-1 Section 2.4.3 for why Method C is recommended.

Can anyone comment on the accuracy of the IEC 60909-0 peak short-circuit current in meshed networks calculated by various software ?
